Think about how many times a day your phone buzzes with an OTP. Bank transfer, Aadhaar authentication, PF withdrawal — everything runs on that one mobile number. Change your number or email, and suddenly half those services stop working.
The tricky part? You can’t just update it in one place and call it done. You need to hit Aadhaar, PAN, your bank, and EPFO separately. Each has its own process.
Below is exactly how to handle each one, step by step.
1. Update Mobile Number and Email in Aadhaar
Aadhaar is where most of your financial identity lives. Get this right first, and the rest gets easier.
If you still have your old number
The Aadhaar app (launched January 2026) lets you update from home:
- Download the Aadhaar app from the Play Store or App Store
- Register with your Aadhaar number, registered mobile, and face ID
- Go to Services > Mobile Number Update
- Enter your new number and tap Send OTP
- Enter the OTP that arrives on your new number
- Do the face authentication — put your face in the red box and blink when asked
- Pay ₹75
- The update takes up to 30 days to process
If you have lost access to your old number
You will need to visit an Aadhaar Seva Kendra in person. There is no online workaround for this. Find the nearest centre here: https://bhuvan-app3.nrsc.gov.in/aadhaar/
- Carry your Aadhaar letter and a valid ID
- They will do biometric verification at the centre
- Fee is ₹75 (same as the app)
Note: As of 2026, the myAadhaar portal only allows address updates online. Name, DOB, and mobile number still need either the app or a physical visit.
Update email in Aadhaar
If you have your registered mobile, email is simpler:
- Go to https://myaadhaar.uidai.gov.in
- Log in with your Aadhaar number and OTP
- Go to Update Aadhaar > Update Demographics Data
- Pick Email and enter the new one
- Verify with OTP
- No fee
2. Update Mobile Number and Email in PAN
Your PAN is needed for tax filings, high-value transactions, and KYC. Outdated contact details mean you might miss important tax communications.
PAN correction (online)
You can do this through Protean eGov (formerly NSDL) or UTIITSL. The process is identical:
- Go to https://onlineservices.proteantech.in or https://www.pan.utiitsl.com
- Select “Changes or Correction in Existing PAN Data”
- Enter your PAN, DOB, and basic details to get a token
- Check the boxes for mobile number and/or email
- Choose Aadhaar e-KYC (paperless)
- Verify with the OTP sent to your Aadhaar-linked mobile
- Enter your new mobile number or email
- Pay approximately ₹101–₹107 inclusive of GST (₹101 at Protean/NSDL, ₹107 at UTIITSL)
- Submit with e-Sign
Your updated PAN card arrives in 15–20 working days.
Faster option: Instant e-PAN
If your PAN and Aadhaar are already linked, this takes minutes:
- Visit https://www.incometax.gov.in/iec/foportal/
- Click Instant e-PAN > Update PAN
- Enter your Aadhaar number and verify via OTP
- Your Aadhaar-linked mobile and email sync to PAN automatically
- You will get a confirmation SMS and email
This only works for mobile and email. Name or DOB changes need the full process above.
3. Update Mobile Number and Email in Bank Accounts
Banks need your current contact details for transaction alerts, statements, and OTPs. The process varies by bank — here is how the big ones handle it.
HDFC Bank
Mobile number:
- Online through Insta Services on the HDFC website
- You will need to verify via Aadhaar e-KYC, and your new number must match what is on your Aadhaar
- Or visit a branch with the Contact Details Updation Form and ID proof
Email:
- Through NetBanking: Go to Profile > Update Email ID
- Or through InstaServices using your registered mobile + DOB/PAN
- Verify the new email with an OTP sent to it
- You will need your debit card details for final confirmation (last 4 digits, expiry, CVV)
- Takes about 48 hours
State Bank of India (SBI)
Mobile number:
- Log in to OnlineSBI and click “Change Mobile Number”
- Enter your new number
- Here is the catch — you must approve this at an SBI ATM using IRATA
- Visit any SBI ATM, swipe your card, enter PIN, go to Services > Others > Internet Banking Request Approval
- Enter the 10-digit reference number you received via SMS
Email:
- Log in to OnlineSBI, go to My Profile > Personal Details > Update Email ID
- Verify with OTP sent to your registered mobile
- Confirmation comes via SMS
ICICI Bank
Mobile number:
- Can only be done by visiting the branch in person
- Fill the account update form and submit with ID proof
Email:
- Log in to Internet Banking, go to Customer Service > Service Requests > Update E-mail ID
- Enter the new email and verify via OTP
- Updated within 1 working day
Quick tips for any bank
- Most banks now insist your new mobile number matches your Aadhaar for online updates
- Keep your debit card handy — you will likely need the last 4 digits, expiry, and CVV
- If the online route fails, just visit the branch with a filled form, self-attested ID, and your passbook
- Email updates are almost always easier than mobile number changes
4. Update Mobile Number and Email in EPFO (UAN)
Your EPFO account needs the right mobile number for PF withdrawal, advances, and KYC. Every important action sends an OTP to your registered number.
Update your mobile number in EPFO
- Go to https://unifiedportal-mem.epfindia.gov.in/memberinterface/
- Log in with your UAN and password
- Click Manage > Contact Details
- Check “Change Mobile No.” or “Change E-mail ID”
- Enter your new mobile number twice (or the new email)
- Click “Get Authorization Pin” — a 4-digit PIN is sent to your new number or email
- Enter the PIN and click “Save Changes”
- Done. Updates are instant.
Forgot password or lost your old number?
- On the EPFO login page, click “Forgot Password”
- Enter your UAN and Aadhaar number
- Verify with OTP on your new mobile number
- Set a new password
- Your new number gets registered automatically
Things to know
- Your Aadhaar must be linked to your UAN. If it is not, the update will not go through
- If the details you enter do not match Aadhaar, the update gets rejected
- Good news: you do not need employer approval for mobile or email changes (that is only for name and DOB)

What to Do First
- Start with Aadhaar. Most other updates depend on your Aadhaar-linked number being current.
- Sync PAN with Aadhaar using Instant e-PAN — it is the quickest route.
- Do banks next. Online updates are mostly Aadhaar-based now, so your new number has to match.
- EPFO is the easiest. Once you log in, the update is instant.
- Save your acknowledgment numbers and note the dates you made each change.
Final Word
Updating your contact details across Aadhaar, PAN, banks, and EPFO sounds like a lot of running around. But honestly? Once Aadhaar is sorted, everything else falls in line quickly. Most of it can be done without leaving home.
Set aside an hour, get it done, and you will not have to deal with that sinking feeling when an OTP lands on a number you no longer use.
